Today, Bitcoin is the world's first decentralized digital currency, whose history began in 2008 when Satoshi Nakamoto published a white paper where he first introduced the concept of a decentralized digital currency independent of banks and governments.

HBO documentary film maker Cullen Hoback has named Peter Todd, a bitcoin core developer who has been involved with bitcoin since 2010, as who he believes to be the real-world identity of Satoshi

Cryptographer Peter Todd has denied he is Bitcoin creator Satoshi Nakamoto, as claimed in a HBO documentary, saying he thinks the director cares more about making a profit than finding out the real identity.
